[0002] During the bearing processing process, the step of adding balls between the outer ring and the inner ring of the bearing is usually called ball assembly. In this step, balls are added to the outer ring or inner ring of the bearing one by one or in batches to ensure that they can move correctly and bear loads in the bearing. This step is an important part of assembling bearings and needs to be operated very carefully to ensure the performance and life of the bearings.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example 1

[0024] See also Figure 1-8 , the utility model provides a technical solution:

[0025] A bearing production positioning mechanism comprises a bearing processing machine 1, a material unloading table 2 and a placement table 3 arranged on the bearing processing machine 1, and also comprises a positioning rod 4, wherein the positioning rod 4 is located on the placement table 3.

[0026] The positioning component 5 is arranged on the placing table 3, and the positioning rod 4 is arranged on the positioning component 5. The positioning component 5 fixes the outer bearing sleeve while the unloading table 2 descends, and simultaneously drives the positioning rod 4 to move to one side, thereby pushing the inner bearing sleeve to fit the inner wall of the outer bearing sleeve.

[0027] The advantage of the positioning component 5 is that it can automatically fix the outer bearing sleeve while the unloading table 2 descends to assemble the ball, and at the same time drive the inner bearing sleeve to fit the inner wall of the outer bearing sleeve to avoid affecting the ball assembly, which greatly improves the work efficiency of the staff during ball assembly. At the same time, it can also ensure that the inner and outer bearing sleeves are accurately positioned to meet the assembly requirements of high precision and consistency, thereby improving product quality.

[0028] The adjusting member 9 is arranged on the positioning assembly 5, and the moving distance of the positioning rod 4 is adjusted according to the size of the bearing through the adjusting member 9.

[0029] The advantage of setting the adjustment part 9 is that the moving distance of the clamping rod 67 and the positioning rod 4 can be quickly adjusted according to the size of the bearing without additional debugging. This design facilitates the work efficiency when assembling ball bearings of different sizes. At the same time, no additional adjustment device is required, which saves adjustment preparation time, helps to improve production efficiency, avoids the cost of additional adjustment tools for bearing sleeves of different sizes, and reduces replacement and maintenance costs. Furthermore, rapid adaptation to bearing sleeves of different sizes means less human intervention, reduces the risk of assembly errors, and improves product quality. The ability to quickly adapt to bearing sleeves of different sizes means higher assembly accuracy and maintains consistency, which helps to improve product quality and performance.

[0030] The positioning assembly 5 includes a clamping member 6 arranged on the placement table 3, and the outer bearing sleeve is clamped and fixed by the clamping member 6. The clamping member 6 is provided with a driving member 7, and the driving member 7 provides power for the clamping member 6 to work. The clamping member 6 is provided with a pushing member 8, and the pushing member 8 drives the positioning rod 4 to push the inner bearing sleeve to fit the inner wall of the outer bearing sleeve.

[0031] The clamping member 6 includes a rotating cavity 61 opened on the placing table 3, a positioning frame 62 is arranged in the rotating cavity 61, a rotating rod 63 is rotatably arranged on the positioning frame 62, a rotating plate 64 is arranged on the rotating rod 63, a plurality of arc-shaped sliding grooves are opened on the rotating plate 64, a plurality of sliding grooves 66 are opened on the placing table 3, the sliding groove 66 is communicated with the rotating cavity 61, a clamping rod 67 is slidably arranged in the sliding groove 66, the clamping rod 67 is slidably connected with the pushing groove 65, a rotating gear 1 68 is arranged on the rotating rod 63, a rotating shaft 69 is rotatably arranged in the rotating cavity 61, and the rotating shaft 69 passes through the rotating cavity 61, and a rotating gear 2 610 engaged with the rotating gear 1 68 is arranged on the rotating shaft 69.

[0032] The advantage of the clamping member 6 is that the multiple clamping rods 67 are in the shape of a regular triangle to fix the outer bearing sleeve, making the outer bearing sleeve more stable.

[0033] The driving member 7 includes an extension rod 71 arranged on the unloading table 2, and an extrusion plate 72 is arranged on the extension rod 71. An extrusion airbag 73 is arranged on the bearing processing machine 1, and a reset spring 74 is arranged in the extrusion airbag 73. A reset plate 75 is arranged on the reset spring 74. A driving warehouse 76 is arranged on the bearing processing machine 1, and an air guide tube 77 is arranged on the driving warehouse 76. The air guide tube 77 is connected with the extrusion airbag 73. A piston plate 78 is slidably arranged in the driving warehouse 76, and a driving rack 79 is arranged on the piston plate 78. The driving rack 79 is slidably connected with the driving warehouse 76, and the rotating shaft 69 is located outside the rotating chamber 61. A driving gear 710 that meshes with the driving rack 79 is provided at one end.

[0034] The advantage of the drive member 7 is that there is no need to add an additional power source to control the movement of the clamping rod 67, further reducing the production cost of ball assembly.

[0035] When the cylinder is started to push the unloading platform 2 down, the extension rod 71 and the extrusion plate 72 descend synchronously with the unloading platform 2, squeezing the extrusion airbag 73, so that the gas in the extrusion airbag 73 enters the driving chamber 76 through the air guide tube 77. At this time, high pressure is formed in the driving chamber 76, which further pushes the piston plate 78 to move, and synchronously drives the driving rack 79 set on the piston plate 78 to move. When the driving rack 79 moves, it also drives the driving gear 710 engaged with it to rotate.

[0036] When the driving gear 710 rotates, it drives the rotating shaft 69 to rotate. The rotation of the rotating shaft 69 drives the rotating gear 2 610 set thereon to rotate. The rotation of the rotating gear 2 610 drives the rotating gear 1 68 engaged with it to rotate. The rotation of the rotating gear 1 68 drives the rotating rod 63 to rotate synchronously. The rotation of the rotating rod 63 drives the rotating plate 64 to rotate synchronously. At this time, the clamping rod 67 in the sliding groove 66 is pushed by the pushing groove 65 on the rotating plate 64 to move along the sliding groove 66 to fix the outer bearing sleeve.

[0037] The pushing member 8 includes a driving screw 81 rotatably arranged in the rotating chamber 61, one end of the driving screw 81 passes through the side wall of the rotating chamber 61, a positioning groove 82 is opened on the placing table 3, the positioning groove 82 is communicated with the rotating chamber 61, the positioning groove 82 is slidably connected with the positioning rod 4, and the driving screw 81 passes through the positioning rod 4 and is threadedly connected with the positioning rod 4, the driving screw 81 and the rotating shaft 69 are located outside the rotating chamber 61, and a transmission pulley 83 is provided at one end, and a transmission belt 84 is provided on the transmission pulley 83.

[0038] The advantage of setting the pusher 8 is that it can simultaneously push the inner bearing sleeve to fit the inner ring of the outer bearing sleeve while fixing the outer bearing sleeve, so that the assembly efficiency of the ball is higher.

[0039] When the rotating shaft 69 rotates, it drives the transmission pulley 83 arranged thereon to rotate, and synchronously drives the transmission pulley 83 arranged on the driving screw 81 to rotate through the transmission belt 84, further drives the driving screw 81 to rotate synchronously, and the driving screw 81 rotates to push the positioning rod 4 threadedly connected to it to move, and the positioning rod 4 moves to push the inner bearing sleeve to fit the inner ring of the outer bearing sleeve.

[0040] The adjusting member 9 includes an adjusting bin 91 arranged on the bearing processing machine 1, an adjusting screw 92 is rotatably arranged in the adjusting bin 91, one end of the adjusting screw 92 passes through the adjusting bin 91, an adjusting plate 93 is slidably arranged in the adjusting bin 91, the adjusting plate 93 is threadedly connected with the adjusting screw 92, an adjusting tube 94 is arranged on the adjusting bin 91, the adjusting tube 94 is connected with the extrusion airbag 73, and an adjusting knob 95 is arranged at one end of the adjusting screw 92 outside the adjusting bin 91.

[0041] When it is necessary to adjust the moving distance of the clamping rod 67 and the positioning rod 4, the staff turns the adjusting knob 95 to drive the adjusting screw 92 to rotate, thereby pushing the adjusting plate 93 threadedly connected to the adjusting screw 92 to slide in the adjusting chamber 91, and pushing the air in the adjusting chamber 91 into the extrusion airbag 73, so that there is more gas in the extrusion airbag 73, and further when the extrusion plate 72 compresses the extrusion airbag 73, the gas in the extrusion airbag 73 can push the piston plate 78 to move a longer distance.

[0042] When in use, the staff first places the inner and outer bearing sleeves on the placement table 3, and makes the inner bearing sleeve pass through the positioning rod 4, and then starts the cylinder to push the unloading table 2 down. At the same time, the extension rod 71 and the extrusion plate 72 follow the unloading table 2 to synchronously descend, and the extrusion airbag 73 is squeezed, so that the gas in the extrusion airbag 73 enters the driving chamber 76 through the air guide tube 77. At this time, high pressure is formed in the driving chamber 76, which further pushes the piston plate 78 to move, and synchronously drives the driving rack 79 set on the piston plate 78 to move. When the driving rack 79 moves, it drives the driving gear 710 engaged with it to rotate.

[0043] When the driving gear 710 rotates, it drives the rotating shaft 69 to rotate. The rotation of the rotating shaft 69 drives the rotating gear 2 610 set thereon to rotate. The rotation of the rotating gear 2 610 drives the rotating gear 1 68 engaged with it to rotate. The rotation of the rotating gear 1 68 drives the rotating rod 63 to rotate synchronously. The rotation of the rotating rod 63 drives the rotating plate 64 to rotate synchronously. At this time, the clamping rod 67 in the sliding groove 66 is pushed by the pushing groove 65 on the rotating plate 64 to move along the sliding groove 66 to fix the outer bearing sleeve.

[0044] When the rotating shaft 69 rotates, it drives the transmission pulley 83 arranged thereon to rotate, and synchronously drives the transmission pulley 83 arranged on the driving screw 81 to rotate through the transmission belt 84, further drives the driving screw 81 to rotate synchronously, and the driving screw 81 rotates to push the positioning rod 4 threadedly connected to it to move, and the positioning rod 4 moves to push the inner bearing sleeve to fit the inner ring of the outer bearing sleeve.
